Competition Process

competition process chart
  • To participate in the L Prize competition, interested manufacturers must provide a letter of intent to submit.
  • Manufacturers must then submit a complete entry package that includes the required technical information, product samples, and a commercial manufacturing plan describing their capability for mass production and distribution of proposed products.
  • During phase one of evaluation, samples of proposed products will undergo performance testing at independent laboratories such as those participating in the DOE CALiPER program.
  • During the second phase of evaluation, the L Prize technical review committee will assess the technical information provided, test results, and manufacturing capabilities.
  • Products that meet the competition requirements will then undergo lifetime testing.
  • At the same time, DOE and utility program partners will coordinate field assessments, using criteria established through the DOE GATEWAY Demonstration program.
  • DOE and partners will also conduct stress testing, subjecting products to extreme conditions.
  • At key stages in the process, DOE may request additional information or follow up with submitters regarding the product or information provided.

Selection of Winners

Entries will be accepted for each product category until a winner is declared, or until 24 months have elapsed since the first award in that category, whichever comes first. In each category, the first entrant to successfully meet the full competition requirements will receive all prizes. Up to two additional entrants may be eligible for program partner promotions.
